Smart Well Technology in Daqing Oil Field

Abstract Daqing oilfield has entered the late period of extra high water production. With the development of horizontal well technology, coning of injected water is one of the most important production problems in the Daqing oilfield. The water cut of many wells in old depleted areas is more than 80%, and still rising. With the use of horizontal well technology in depleted areas, the problem will continue. An adjustable water system or smart well (intelligent completion) technology is urgently needed to solve the practical production problems in this oilfield. This article first identifies the smart well (intelligent completion) technology, and the major companies using it. Secondly, the paper shows the development of smart well technology in China, the reason why we use smart well technology in the Daqing oilfield, the adjustable water cut system in the Daqing oilfield, and the application of smart well technology in the Daqing oilfield. Finally, a smart well is introduced, and some of advanced downhole devices and the prospects for their application in the Daqing oilfield are detailed.
